Patent CA-2418250-A1 (CA)
Title: Method for reducing stimulated brillouin scattering in waveguide systems and devices
Inventor: DRAGIC PETER
IPC: G02F1/35
Filed: 2001-08-13
Abstract: The method of the invention controls the acoustic waves to be guided away fr om the portion of the waveguide which guides the light. Thus, acoustic waves ar e guided into the cladding (12). A substantial reduction in the SBS effect is then realized in the core that guides light. The method of the invention is applicable to single clad optical waveguides, such as optical fibers, as wel l as dual clad optical fibers and other waveguides. A preferred dual clad (a.k.a. dual core) waveguide structure permits realization of a pump laser system having reduced SBS effect in the core used for guiding transmitted light to be pumped (amplified). A second core (12) guides acoustic waves outside the core (10) used for guiding transmitted light, and also guides pu mp light which amplifies the light transmitted in the core for light transmission. Pumping may also be assisted by cladding the second "pump" cor e (12) with a cladding (20) that is anti-guiding for light and guiding for acoustic waves.

Patent CA-2433440-A1 (CA)
Inventor: NISSEN JOHN CHRISTIAN DOUGHTY
IPC: G10L21/06
Filed: 2001-12-31
Abstract: This invention concerns a system of communication including a tactile device for single-handed input of phonetic information and a corresponding tactile device for output of that information onto a single hand. The phonetic information input using the tactile input device can be output as synthesized speech, and the tactile output device can receive phonetic information obtained from a speech recognition engine. Thus the input device acts as a "talking hand", and the output device acts as a "listening hand". The phonemic information is suitable for tactile or speech output, either directly or indirectly, locally or remotely, via a transmission system such as a telephone network. The system involves a scheme in which the fingers are used for consonants and the thumb for vowels, with fingers and thumb used together for voiced consonants.
